A device thought to be the largest tidal energy turbine to be built in the world has been described by its developer as “simple and robust”.
Atlantis Resources unveiled its AK-1000 at Invergordon ahead of it being towed on a barge to a European Marine Energy Centre test site off Eday, Orkney…The device has two sets of blades to harness ebb and flood tides.
Mr Cornelius told BBC Scotland that the focus of the marine industry at the moment was making the Pentland Firth a huge success in terms of generating electricity from renewable energy devices…
“It is one of the harshest environments on the planet…In order to get a robust turbine we have had to make what we call ultimately the dumbest, simple but most robust turbine you could possibly put in such a harsh environment.”
The AK-1000′s two sets of blades have also been designed to move slowly underwater and Atlantis said they would not pose a threat to sea life…
Atlantis, which has bases in London and Singapore, has been leading a plan to use tidal energy to power a computer data centre in the far north of Scotland…
The computer data centre would provide services for a number of companies and be powered by tidal energy rather than depend on electricity supplied to the National Grid.
I guess this puts the Brits+Singaporeans – and anyone else putting such projects into play – years ahead of that great industrial and engineering giant, the United States.
Between Republicans who prefer to spend taxpayer dollars on their favorite war contractors and Democrats who are happy enough maintaining bureaucratic sinecures, the United States should regain a leadership position in the global economy – never.
An Ohio company is seeking to anchor barges at 11 spots along the Ohio River, including Louisville, as part of a potential $22 million “green” initiative to turn river current into electrical current.
The barges, with submerged turbines, would each generate relatively little electricity — enough to power about 260 typical homes…
The Ohio River project, proposed by McGinnis Inc., of South Point, Ohio, would include one barge anchored just below the McAlpine dam in Louisville and near the locks in an area that isn’t used for navigation. The 10 other Ohio River sites also would be located just downstream from existing dams…
The McAlpine project, like its other McGinnis counterparts, would consist of a 100- to 300-foot barge, 20 to 52 feet wide, anchored by steel poles, according to documents filed with FERC.
Ten turbines about 7 feet wide would be mounted along the sides of the barge.
An armored high voltage line would run from the barge to an existing power line nearby, to plug into the electric grid…
McGinnis said he’s willing to invest as much as $2million developing each of the 11 stations, along with two more on the Kanawha River in West Virginia.
Yup. I still get pissed off about the fact that we could have been doing this for thirty years or so. Thank the candyass Blue Dog Democrats who thought the sun rose and set in Ronald Reagan’s butt for that hiatus in alternative energy experiments.
People like McGinnis have always had the smarts and experience to build projects like this. Given the chance – instead of government and corporate opposition.
A Whalepower test blade
A West Chester University professor has developed a new wind turbine that draws inspiration from a blubbery source: the flippers of a humpback whale. Those knobby flippers were long considered one of the oddities of the sea, found on no other earthly creature.
But after years of study, starting with a whale that washed up on a New Jersey beach, Frank Fish thinks he knows their secret. The bumps cause water to flow over the flippers more smoothly, giving the giant mammal the ability to swim tight circles around its prey.
What works in the ocean seems to work in air. Already a flipperlike prototype is generating energy on Canada’s Prince Edward Island, with twin, bumpy-edged blades knifing through the air. And this summer, an industrial fan company plans to roll out its own whale-inspired model – moving the same amount of air with half the usual number of blades and thus a smaller, energy-saving motor.
Some scientists were sceptical at first, but the concept now has gotten support from independent researchers, most recently some Harvard engineers who wrote up their findings in the respected journal Physical Review Letters…
It has all been a bit of a culture shock for Fish, who is more at home in the open world of academia than the more secretive realm of inventions and patents. Two decades ago, his only motivation was to figure out what the bumps were for.
“I sort of found something that’s in plain sight,” he says. “You can look at something again and again, and then you’re seeing it differently.”
A long, thoroughly enjoyable in-depth article. Read it and reflect.
Could be a beginning to advancements in technology in wind generation. Cripes – this may be useful in aerofoil design in general.
